Often, however, the churches are more coy about it, and just say they are "Christian" or "Non-Denominational". What ways are there to tell if a church is teaching Christian Reconstructionism? Or is Pentecostal/Charismatic (or some variation)? Or is supporting Dominionist causes and organizations? Or is preaching dangerous attitudes like "name it and claim it" prayer and regular "chastening" of children?

What should we be looking for when we run across a church? I mean, even if they want to hide their true nature from outsiders, they still want to attract like-minded people, so I assume they would keep their beliefs somewhat visible, even if it's encoded in some way, don't they? Or is that not a safe assumption?
